Quick Answer
The most common dryer issues are not heating, not spinning, taking too long to dry, and smelling burnt — each has a typical cause that can often be narrowed down with a few simple checks before calling a technician.
Not heating and taking too long are related but distinct symptoms — one means zero heat, the other means reduced efficiency.
Most dryer issues fall into one of four categories. Here's how to troubleshoot each one before deciding whether you need a technician.
Not Heating
- Check the external vent flap for airflow
- Check the lint filter is clean
- If both are clear, the issue is likely a thermal fuse, heating element, or gas valve
Not Spinning
- Check the door is closing fully
- Listen for a humming sound — may indicate a snapped belt
- Check the load isn't too large or unbalanced
Taking Too Long to Dry
- Check the vent and filter for blockages
- Avoid overloading the drum
- Sort loads by fabric type and weight for more even drying
Smelling Burnt
A burnt smell can indicate lint accumulation near the heating element. Switch the dryer off and have it inspected before running it again — don't continue using it to 'see if it goes away'.
Frequently Asked Questions
What's the first thing to check if my dryer isn't heating?▼
Check the external vent flap for airflow first — a blocked vent is the most common cause of heating faults.
Why is my dryer taking two cycles to dry one load?▼
This is usually caused by reduced airflow from a blocked vent or filter, or from overloading the drum.
Is a burnt smell from a dryer always serious?▼
Treat it as serious until checked — it can indicate lint build-up near the heating element, which is a fire risk if ignored.
Can I troubleshoot a dryer not spinning myself?▼
You can check the door latch and load size yourself, but if the drum motor or belt has failed, it needs a licensed technician.
